Import patches-unapplied version 9.27~dfsg+0-0ubuntu1 to ubuntu/eoan-proposed

Imported using git-ubuntu import.

Changelog parent: a0af6cdfdfee00341f6a53d1802dea4d81c36846

New changelog entries:
* New upstream release
Highlights:
- We have extensively cleaned up the Postscript name space: removing
access to internal and/or undocumented Postscript operators, procedures
and data. This has benefits for security and maintainability.
- Fontmap can now reference invidual fonts in a TrueType Collection for
font subsitution. Previously, a Fontmap entry could only reference a
TrueType collection and use the default (first) font. Now, the Fontmap
syntax allows for specifying a specific index in a TTC. See the comments
at the top of (the default) Fontmap.GS for details.
* Improvements on HTML documentation (Use local JavaScript, avoid remote
fonts, avoid Google Tag Manager) by overtaking the appropriate patches
from the Debian package.
* Backported upstream patch to fix regression resolving bounding box of
font glyphs and re-introduce over/underflow workaround.
* Backported upstream patch to protect use of .forceput with
executeonly.
* Removed patches 02018*, lp1815339*, CVE-2019-* which are already included
upstream.
* Refreshed patch 2007_suggest_install_ghostscript-doc_in_code.patch with
quilt.
* debian/libgs9.symbols: Updated for new upstream source. Applied patch
which dpkg-gensymbols generated.
